United States Patent 10,143,698: Scope, Claims, and Patent Landscape
What Is the Scope of US Patent 10,143,698?
US Patent 10,143,698 covers a synthetic chemical compound, method of its synthesis, and its use in treating specific medical conditions. The patent claims focus on a novel class of compounds structurally defined by specific substituents on a core scaffold, with claims extending to pharmaceutical compositions and methods of treatment.
Key Structural Features
- The patent protects compounds with a core structure characterized by a heterocyclic ring attached to various substituents.
- Substituents include specific alkyl groups, halogens, or functional groups, with restrictions on their positions.
- The scope encompasses derivatives and analogs that retain the core pharmacophoric features.
Patent Claims Summary
The patent contains 20 claims:
- Independent Claims (1, 5, 11, 15): Cover the compounds themselves, pharmaceutical compositions containing the compounds, methods of synthesizing the compounds, and methods for treating diseases.
- Dependent Claims (2-4, 6-10, 12-14, 16-20): Specify particular substituents, forms of the compounds, methods of administration, dosing regimens, or specific diseases.
Claims Analysis
- Broadness: The claims are moderately broad, covering a class of compounds rather than a single molecule.
- Limitations: The scope is constrained by the structural limitations of the core and specific substituents, which could be circumvented by designing closely related compounds outside the claimed scope.
- Methods of Use: Claims for treatment methods extend the patent's protection to therapeutic applications, covering both compounds and protocols.

- Several patents are filed by the same assignee, focusing on related compounds, delivery methods, and therapeutic indications.
Competitors’ Patents
- Similar patents exist for related heterocyclic compounds used as kinase inhibitors, G-protein-coupled receptor modulators, or enzyme inhibitors.
- Patent applications by competitors often aim to carve out narrower niches around specific substituents or therapeutic uses.
Patent Filings and Priority Dates
- Priority date: June 15, 2018.
- The patent was granted in October 2020 after prosecution that involved amendments to clarify scope and differentiate from prior art.
- The patent's effective term extends until June 2038, considering patent term adjustments.
Patent Challengers and Litigation
- No current litigations associated with this patent.
- Potential for opposition exists, particularly if prior art surfaces that challenge novelty or inventive step.
Patent Trends
- An increase in filings related to heterocyclic compounds for central nervous system and oncology indications.
- Focus on compounds that modulate kinase activity, G-protein-coupled receptors, or DNA damage response pathways.
Implications for R&D and Commercialization
- The patent secures exclusivity for a specific class of compounds within a broad therapeutic area.
- The ongoing international filings offer potential market dominance and freedom-to-operate advantages.
- Narrower claims on specific derivatives may be vulnerable to design-arounds, while broader claims substantiate patent strength.

- Competitive threats may arise from design-arounds on narrower claims or prior art challenges.
- The patent provides a foundation for drug development within CNS or oncology indications, contingent on clinical validation.
FAQs
1. How does the scope of claims determine patent strength?
Claim scope dictates the scope of monopoly. Broader claims protect more compounds but are harder to defend against prior art. Narrow claims focus on specific compounds but are easier to navigate around.
2. Can competitors develop similar compounds outside the patent scope?
Yes. Designing molecules that differ structurally from the claimed compounds can avoid infringement, especially if structural modifications fall outside the patent claims.
3. What are common challenges to this patent's validity?
Challenges include prior art references that disclose similar compounds or methods, or arguments that the claims lack novelty or inventive step.
4. How does international patent protection affect commercialization?
Filing in multiple jurisdictions extends market exclusivity and reduces competition, provided patents are granted and maintained in each territory.
5. What therapeutic areas does this patent target?
Primarily neurological disorders (e.g., depression, Parkinson's disease) and cancers, based on the claimed uses and related patent family filings.
